Background An active conflict in South Sudan in late 2013/early 2014 displaced approximately 2 million people over the course of several months. In May 2015, the International Rescue Committee and UNICEF conducted a mixed-methods case study of the impact of that acute emergency on integrated community case management (iCCM) of childhood illness programming Payinjiar County, Unity State. The objective was to document the operations of an iCCM program during an acute crisis and to assess the program's ability to continue operations. Results This mixed-methods case study is comprised of semi-structured interviews and focus groups with key stakeholders such as policymakers, program implementers, community health workers (CHWs), and caregivers on their experience with iCCM programming during this time period. Routine program data were also analyzed to assess the effect of the crisis on key health indicators. Findings Internally displaced persons (IDPs) nearly doubled the population in Payinjiar. Some displaced CHWs continued to provide treatment. in host communities when they were able to take supplies with them. Despite no formal community mobilization effort by the iCCM program, many IDPs identified CHWs in the communities they were displaced to and obtained care from them. Caregivers who had been internally displaced reported preferring care from CHWs especially in contrast to risking an insecure journey to health facilities. The total number of treatments provided per month by CHWs dropped during the acute crisis, but recovered to pre-crisis levels with in six months. CHW supervisors attempted to continue supervision by utilizing their networks to track down displaced CHWs and assess the security situation prior to visits. The monthly supervision rate dropped to the lowest level of 77% in February 2014, but rebounded to 91% by August 2014. Several CHWs and community leaders qualitatively validated this claim of sustained supervision. Conclusions CHWs, including those who were internally displaced, continued to provide treatment for childhood illnesses during an acute emergency, and service provision recovered faster to pre-crisis levels than the formal health sector. International donors and humanitarian actors should recognize iCCM as a potentially high-impact humanitarian response. Flexible funding from donors would enable further evidence generation on iCCM, approaches and improvements that could both sustain and enhance programming in acute crisis.
